I did and that's what i don't get, it seams two of them are plus and the other is minus. It's logical up until now. But I thought one of them should be connected to the light, and when I turn the light on there should be current. Right now there is always power to both pluses

The problem is that there is no back light on the clock. The clock works well, but no light. From what I remember there should be a light, right? (I haven't had my clock connected for years and I am not sure)
